| Abstract: | The method of adaptive interference cancellation based on LMS algorithm is introduced.It also discusses the adaptive frequency block LMS algorithm,and describes maths deduction of the algorithm and the model of the system.The performance of LMS is demonstrated throuth Matlab simulation under the conditions of wide band interference,single-tone interference and chirp interference.Simulation shows that LMS can remove three interferences effectively and improve the quality of signal transmission. |
